Battery Backup Setup for xPAP

The following battery backup design is under edit. I will continue to edit it here until it is complete. At that time, I will move it into the Wiki. However, I thought you might enjoy seeing it come together. It might help those of you who want to put together a battery backup setup. And of course, I welcome input, though remember - I am sharing what I've done over the years - not a generic approach. But I am trying to make it generic enough for everyone else to pick up and use.

Introduction

Objectives

First, with this setup, if you know there is a possibility power may be interrupted, you can plug into this setup and use the battery. If power goes out, the setup is such that your xPAP unit can continue uninterrupted. When power is restored, the battery tender will gradually recharge the battery to full capacity.

Second, the design is fairly modular to allow you to customize this. You can keep it simple, or go a bit more complicated and make it sturdier.

Third, this is designed to stay in the bedroom. No need to drag the battery in and out of the house. But it is also designed to allow you to make it so little fingers won't be hurt with this setup.

Special Features

This setup allows you to use a modular approach to the power setup. You can choose your battery size. You can choose amount the battery tender options. You choose the shared use option. Make it as simple or as sturdy as you need. You can choose the DC to xPAP hookup. Choose the options to suit your needs. This approach means you can configure this to meet your needs. Additionally with this type of setup, it will help the battery last longer than if it is stored without the "float" charge, which keeps the battery charged and ready to use.

Note about Web sites

I have no affiliation with any of the web sites. I selected and used these products to make this setup for myself. Feel free to tinker and adapt it as you see fit.

Note about the application

I researched this as best as possible. I've used deep cycle batteries and an inverter for the past 10 years. However, this is the first setup I designed to stay indoors to provide continuous power. Though it should work and others will help improve the design, please understand if you use this design, you will do so at your own risk. (But it should work for you, if you follow the directions).

Note about the construction

By making this a modular design, you can either do some minor customization, or use a simpler approach to connect the components. I took an approach that does a good job of anchoring all the pieces. The advantage of this is that no parts will accidentally short. Nor will it allow little fingers to accidentally be hurt.

Note about humidifier use

Humidifiers consume a lot of power. ResMed humidifiers require pure sine wave inverters, which are both more expensive and use much more power. Thus, this design is primarily intended to be used without a humidifier. The humdifier can be attached, but turned off. It will then function as a "passover" humidifier.
